I have table names in this form: MY_TABLE MY_TABLE_CTL MY_TABLE_DEL MY_TABLE_RUN YOUR_TABLE YOUR_TABLE_CTL YOUR_TABLE_DEL YOUR_TABLE_RUN I am trying to create a regular expression that will return true for only these tables: MY_TABLE YOUR_TABLE I tried these: pattern = re.compile(r"_(?!(CTL|DEL|RUN))") pattern = re.compile(r"\w+(?!(CTL|DEL|RUN))") pattern = re.compile(r"(?!(CTL|DEL|RUN)$)") But, both match. I do not need to capture anything.
